The dropouts are occuring while connected via ethernet to the router. It is consistent across devices, and leads to periodic dropouts and lag spikes while gaming or streaming video throughout the day. I have tried a hub reboot/reset, with no improvements 😞 Do all of the power levels look normal and correct? It has been this way since it was installed last month, so I dont believe that it is something that has developed, but rather has been this way throughout.
Power levels are all within limits, though the upstream power is bouncing along very close to the lower values permitted (34-49 dBmV in my book), and the downstream data is showing a few post-RS (uncorrected) errors breaking through
There's also something well odd about your BQM - look at the image you first posted, and then the link below. At first glance they're very similar, but on closer examination they are different days (and it seems the link is "live"). Now look at 2am to 4am. Near enough identical. I can't say what is causing that, but it's extremely odd, which may or may not help.
